Great Qin: From the Start, I Invent a Long-Lived Imperial Heir

After transmigrating to the Qin Empire, he finds himself a prisoner in a death cell from the start, with the punishment of being torn apart by chariots just around the corner! At the brink of life and death, he awakens the [Causality Reversal System]: as long as his logic is airtight, whatever Ying Changsheng says becomes the truth! When Emperor Qin Shi Huang inspects the death cells, I throw caution to the wind. "Father! Your son survived falling off a cliff all those years ago, and has returned with the secret of immortality!" [Ding! The First Emperor's belief level is 100%. The lie has become reality! Congratulations, Host, you have obtained: True Dragon Destiny + Immortal Bloodline!] That day, the eternal emperor shed tears in the death cell and roared at his ministers: "If anyone dares lay a finger on my son, I'll wipe out his entire clan!" From then on, the Qin Empire had a crown prince even more domineering than the First Emperor, a complete "madman." Zhao Gao points at a deer and calls it a horse? I point at Zhao Gao and call him a dog, and he has to bark on the spot! The Xiongnu cavalry invade from the north? Three thousand elite Qin soldiers with firearms will teach their chanyu a lesson! Years later, the First Emperor looks at the Qin Empire's empire on which the sun never sets, his hands trembling. "My son, is the Earth... really round?" I smile calmly. "Father, wherever the sun and moon shine is Qin territory!"
